Well, good sir (or ma'am), it very well may have been the issue. I do recall dutifully remove the previous adhesive, but I did not use alcohol to ensure all residue was removed from the frame. The LCD was brand new, so no adhesive. In retrospect, that may have been the issue. You live and you learn. And sometimes you pay. Macs are not exactly user friendly to disassemble. But, well, I am obviously a genius and by god if I'm not going to let some piece of electronics taunt me. Lesson learned. Lesson learned.
